How to start transaction in custom login module?

[nish_dce]

Hi All,
I again have a problem for which I have no clues!;o(
Actually, I need to perform some direct Database updation before each EJB method call,so I want to put it in the "CustomLoginModule" itself,as it would be executed per EJB method call.
The issue is that I want to rollback any changes I do during LoginModule;if my actual EJB method call fails.

That is,the database updation as well as method call invocation should be a part of "one" transaction only!
Is it possible?

Any help would be highly appreciated!

Thanks in advance,
Newbie

This won't work, as the login module is not called for each ejb request (the security manager caches this info).

So put this direct database update in a sessionbean and put them together in one (ejb) transaction. I pretty sure it is impossible to combine ejb transactions with transactions started in a login module, because these are two completely separated tasks.
